Works great! I bought it to share with my grandson. He loved it. So did His parents. We decided to leave it here at our house. It will be a treat when coming to visit. Customer service and guarantee are great as well!
A great little engine, and a fantastic conversation starter! Pretty well made, and runs like a champ. Runs just fine on 91% rubbing alcohol from CVS. It will not run on 70% rubbing alcohol, as it there is not enough alcohol to keep the wick lit.
I like this product very much , it help for science study
Wow, what a cool model! This is the second stirling engine that I have received. The first one I received as a gift and it looks like a piece of art . This one is just as impressive, but looks homemade. At $33 USD it is an absolute bargain. I will likely select another model from this vendor to add to my collection. Further, I am tempted to buy several more of these to hand out as very awesome and unique gifts.
